Deploying Containers in AWS with Terraform

In recent years, containerization has become an increasingly popular method for deploying and managing applications in the cloud. Amazon Web Services (AWS) offers a range of containerization services, including Amazon Elastic Container Registry (ECR), Amazon Elastic Container Service (ECS), and Amazon Elastic Kubernetes Service (EKS). In this chapter, you will learn how to use Terraform to deploy containers in AWS, from selecting and designing the appropriate infrastructure to developing and deploying your container infrastructure.

Get ready to dive into the world of containerization and learn how to deploy containers in AWS using Terraform with the following topics:

• What are containers?
• AWS containers
• How to utilize Terraform for containers
• How to use Terraform for AWS container resources

What are containers?

Containers are a type of virtualization technology that allows developers to package up an application and its dependencies into a single container, which can be easily moved between different environments. Containers provide a consistent environment for the application to run in, regardless of the underlying infrastructure. They are lightweight and efficient, as they share the host operating system kernel and do not require a full virtual machine (VM). Popular containerization platforms include Docker and Kubernetes.

Containers offer a more lightweight and efficient alternative to VMs. In essence, a container is a self-contained, portable, and executable package that contains all the necessary components to run specific software, such as the code, runtime, libraries, environment variables, and configuration files. Because containers provide a consistent environment for the application to run in, they are well suited for use in various environments, including...

AWS containers

In AWS, containers refer to a way of packaging and deploying applications as container images. These container images can be run on AWS services such as Amazon ECS and Amazon EKS.

Amazon ECS and Amazon EKS are explained in the Containers in AWS section, so we won’t repeat them here.

AWS Fargate is a serverless compute engine for containers that allows you to run containers without having to provision and manage the underlying infrastructure. With Fargate, you only pay for the resources that your containers use, and there is no need to manage the underlying EC2 instances.

Amazon ECR is a fully managed container registry service that makes it easy to store, manage, and deploy container images. ECR is integrated with other AWS services such as ECS and EKS, making it easy to store and retrieve container images for use in those services.

AWS App Runner is a fully managed service that makes it easy to build, test, and deploy containerized applications quickly...

How to utilize Terraform for containers

Terraform provides a powerful platform for managing and deploying container infrastructure on AWS. With Terraform, you can easily create and manage resources such as ECR, ECS, and EKS. This section will cover the basics of how to utilize Terraform for containers, including selecting and designing container infrastructure with Terraform, and how to develop and deploy container infrastructure using Terraform.

Deploying containers with Terraform

Terraform is a tool that allows you to define, provision, and manage infrastructure as code. To design a container using Terraform, you can use the docker_container resource to create, configure, and manage a container.

Here is an example of how to use Terraform to create a container:

resource "docker_container" "example" {
  name  = "example-container"
  image = "nginx:latest"
  ports {
    internal...

How to use Terraform for AWS container resources

There are several ways to deploy containers in AWS, depending on your specific requirements and use case. Here are the general steps to deploy a container in AWS:

1. Build and push your container image to a container registry such as Amazon ECR or any other public or private registry
2. Choose a container orchestration platform such as Amazon ECS, Amazon EKS, AWS Fargate, AWS Lambda, AWS Elastic Beanstalk, or AWS App Runner
3. Create a task definition or Pod definition that describes the container image and its configurations, such as environment variables, ports, and volumes
4. Create a service or deployment that uses the task definition or Pod definition to launch one or more instances of the container
5. Optionally, configure scaling, load balancing, and monitoring for your containerized application
6. Optionally, you can use services such as Terraform or AWS CloudFormation to automate the deployment and management of your...

Summary

In conclusion, containers are a powerful tool for packaging and deploying applications in a consistent and portable way. AWS offers a variety of container services and platforms, each with its own set of features and capabilities. Terraform is an infrastructure-as-code (IaC) tool that can be used to manage and provision resources in AWS, including containers. By using Terraform to deploy containers to AWS, you can automate the process of creating and managing containerized applications, and ensure that your infrastructure is consistent, repeatable, and versionable. This can greatly simplify the process of deploying and scaling applications, and allows you to focus on the business logic of your application rather than managing the underlying infrastructure.

In the next chapter, we’ll take a closer look at how Terraform can be leveraged for enterprise-level AWS projects. You’ll learn about the unique challenges and considerations that come with managing large...
